My invention aims to provide an improved elevator or lifter and support,part cularly adapted for the application of wall-boards to ceilings.

One of the main objects of my invention is to provide an improved lifterand support that will enable a single carpenter to apply wall-board withgreatease and despatch to ceilings.

Other objects and advantages of my in-- vention will appear in thespecification, when considered in connection with the illustra.

tive embodiment thereof shown in the accompanying drawings, in which:

Figure 1 is a side elevation of an elevator and support embodying myinvention;

Figure 2 is a top plan view of the support ing frame shown in Figure 1;

Figure 3 is a central longitudinal sectlonal view of the device shown inFigure 1; Figure 4 is a bottom plan view of the base or pedestal shownin Figures 1 and 3; and

Figure 5 is a cross sectional view taken on the line 55 of Figure 1.

Referring particularly to the drawings, I have there shown the preferredform of my elevator and support carried on a suitable base, preferablyformed by securing three legs to split and outwardly flared ends of apiece of ordinary tubing 11.

Telescoped and removably mounted within the tube 11, I have shown atubular extension 12 made of two pieces of pipe joined by a coupling 13,which serves as a shoulder to rest on top of the tube 11 (Figures .1 and3). This tubular extension is adapted to receive a standard 14, alsoconveniently" made of tubing. In the upper end of the standard, I haveshown a plug 15, having integral, ears 16 to which brackets orsupporting arms 17 are secured, each preferably by a single bolt (Figure2).

Carried by the bracketsv or supporting arms 17 is a frame 18, suitablymade of four wooden strips, The frame 18 is made so as to support piecesof commercial wall board, and is constructed and arranged to tilt oryield slightly about pivots to lift the wall ing or somwhat irregular,and to extend at right angles to the standard 14 when the ceiling ishorizontal.

.I find that it 1s desirable, although not indispensable, to connect theopposite end pieces of the frame 18 by a bracing chain 19, shown inFigure 2 as having branched ends 20 secured by eye bolts 21 to. thesepieces near their bolted connections with thearms 17. I The chain ispreferably stretched longitudmallyacross thejframe about. on a levelwith the top thereof,and is adapted-to support the middle of the wallboard to prevent it from sagging. 7 To raise and lower the frame .18with a:- piece of wall board on it, I have showna winding drum 22(Figures 1, 3 and 5) in the 7 form of a Windlass journalled in aU-shaped,

sheetmetal clamp 23 bolted around the tubular extension 12 above thecoupling 13.

A rope or chain 2 is wound on the Windlass and operatively secured tothe lower end of the standard 1 1. Herein, a -cap 25 having a lateralarm 26, is screwed on the end of the tube 14: to provide an offsetconnection for the chain, so that it will pull more nearly vertically. I

To lock and hold the frame in any adjusted position, I have shown on thedrum shaft, a ratchet wheel 27 and a dog 28 (Figure 1). This permits thecarpenter to elevate aboard to nailing position, and then' devotehis'whole attention to driving the nails. "Moreover, he can operate thewindlass without climbing down from the usual workhorse, because it ishigh enough to be within easy reach. 7

From the foregoing description, it is clear that my elevator and supporteliminates the necessity for a helper toassist in lifting and holdingboards 1n place and, consequently,

cuts down the cost of labor. Further itenables a carpenter to give hiswhole attention to setting the board and nailing it properly. Iteliminates waste due to'breakagebecause the frame affords a stablesupport-'forthe boards and )revents them from fallin Moreover, thedevice can be made at a very low cost, and can be manipulated by anordinary unskilled laborer;

Having thus described one embodiment of my invention with theunderstanding that it is not limited thereto, what- I claim and desireto secure by Letters Patent is: 1

1. A device for elevating wall boards and and mechanical means to raisesaid standard.

2. In a device for elevating wall boards and the like to ceilings andsupporting them in place ready to be nailed; a pedestal comprising atubular portion having a slitted lower end; the slitted portions beingbent outwardly at an angle to the axis of said tubular portion; legssecured to the bent standard portions; a standard teleseoped within thetubular portion; means for elevating the and aframe yieldably connectedto the standard.

3. A support for'holding Wall boards in place ready to benailed to aceiling comprising, in combination, a base member a tubular standardadjustably supported on the base member; an open rectangular framesupported on the tubular standard; a yieldable connection between theopen frame and the standard; and chains secured to some of the oppositesidesof said frame to support the boards therebetvveen.

In testimony that I claim the foregoing as my 0WI1,-I have heretoafiixed my signa- .ture. I AIN AUSTIN.
